when asym divs probs sum to >1, exit with msg

[drbergman]

@heberlr first identified this behavior and a discussion led to opening #347. While better handling of thrown exceptions would be an improvement, for now have this error behave like all others and exit(-1).

previously, used throw but the standard main.cpp catches the exception and still exits with 0

• The use of 'pCD_parent' appears to be incorrect as the function parameters use 'pCell_parent'. This likely introduces a bug if 'pCD_parent' is not properly defined.

std::cerr << "Error: Asymmetric division probabilities for " + pCD_parent->name + " sum to greater than 1.0 and cannot be normalized." << std::endl;
